Dr. Chino talks with Dr. Navneet Majhail and patient advocate Laurie Adami about CAR-T therapy, an advance cancer treatment that biologically engineers a patient's own T-cells to recognize and kill cancer cells. This discussion will be based off the JCO OP article, "Outpatient Administration of Chimeric Antigen Receptor T-Cell Therapy Using Remote Patient Monitoring," on which Dr. Majhail served as lead author. TRANSCRIPT Dr. Fumiko Chino: Hello, and welcome to Put into Practice, the podcast for the JCO Oncology Practice. I'm Dr. Fumiko Chino, an associate professor in radiation oncology at MD Anderson Cancer Center with a research focus on access, affordability, and equity. CAR T-therapy is an advanced cancer treatment that biologically engineers a patient's own T cells to recognize and kill cancer cells. It has shown remarkable benefits, leading to long-term remission or even cure for select patients with hematological cancers that have not responded to other treatments. Primary trials were exclusively conducted in the inpatient setting due to high risk of quick onset and life-threatening toxicities requiring close monitoring and immediate treatment. Advances in symptom monitoring and care delivery have allowed the introduction of outpatient CAR T, which is cost saving and more patient centered. I'm happy to welcome two guests today to discuss this promising operational shift. Dr. Navneet Majhail, MD, MS, serves as the Physician-in-Chief of Blood Cancers at the Sarah Cannon Cancer Network, where he oversees 10 transplant and cellular therapy programs that collectively perform over 1500 transplants and cellular therapies each year. He is the first author of the JCO OP manuscript, "Outpatient Administration of Chimeric Antigen Receptor T-Cell Therapy Using Remote Patient Monitoring," which was published earlier this year. Ms. Laurie Adami was President of the LA-based Interactive Data's Fixed Income Analytics Division when she was diagnosed with stage four follicular lymphoma at age 46. From 2006 to 2018, she was in continuous treatment and received multiple lines of therapy, including three clinical trials. In 2018, she received treatment number seven, a clinical trial of Kite CAR T-therapy. Thirty days later, she was in complete remission, where she remains today. She is an active patient advocate and legislative policy advocate for several not-for-profits. Our full disclosures are available in the transcript of this episode, and we have already agreed to go by our first names for the podcast today. Navneet and Laurie, it's so wonderful to speak to you today. Dr. Navneet Majhail: Thank you. Looking forward to this conversation. Laurie Adami: Thank you, Dr. Chino. I guess I'm supposed to call you Fumiko. Great to be here today. Great to be alive, first of all, and great to be here on this call. Thank you for having me. Dr. Fumiko Chino: I think with everything you've gone through, Laurie, we all go on a first name basis. Now, Navneet, do you mind starting us out with a short history of CAR T in the US, including the side effects and the precise care delivery needs that were the initial reasons why care was limited to the hospital? Dr. Navneet Majhail: So, Fumiko, you laid an excellent background as to why these therapies are done in the inpatient side and what they are. I mean, it's really exciting, right? These are what we call transformative therapies in oncology or medicine as a whole. You're taking patients with very, very advanced diseases who traditionally would have gone on to hospice, where you can potentially put around half of these patients into very deep remissions, and maybe some of them might be cured of their underlying malignancies. Now, having said that, as you alluded to in the introductions, most of the trials early on were focused entirely on the inpatient space for a few reasons. One was the unknowns. These were early therapies, unknown side effects, you needed to have that monitoring. The second, some of the very early work that was done with these therapies, it was clear you can have some potentially severe and fatal side effects, like cytokine release syndrome, what we now call ICANS, or immune effector cell-associated neurotoxicity syndrome. You have issues such as HLH, hemo-phagocytic lymphohistiocytosis. These are some really fatal, potentially fatal and severe side effects, which really needed close monitoring on the inpatient side. As things have evolved, obviously we've gotten smarter at selecting patients. The constructs have improved as well, where the incidence and the severity of these toxicities has gone down. And as we become smarter overall, both from a supportive care, patient selection and technology perspective, certainly there are opportunities now for us to look at delivering these care where patients can access these therapies better. Dr. Fumiko Chino: That's a wonderful summary, and I know at this point, I believe over 300 sites are Foundation for the Accreditation of Cellular Therapy accredited to deliver CAR T-cell therapy. So, we really have gone very much into the space where we're trying to expand access to these therapies. Now, Laurie, I know that your CAR T was in 2018 on a phase two trial at UCLA, but your treatment started in 2006. Do you mind walking us through what that was like for you? How did it go? What was required in terms of travel, time, for, I know, again, just not just yourself, but also your family, and it's through the treatment and then also the recovery? I'm presuming that you had to be in the hospital, for example, for your CAR T for at least a week, if not longer. Laurie Adami: Yeah, I was diagnosed in 2006 and spent 12 years in continuous treatment, all in Los Angeles where I live. When I did my CAR T, I was also in Los Angeles, so that made it easier for me, as well as my family, because when I went in for CAR T, I was just at the UCLA main hospital, which is about 20 minutes drive from my home. The process for 12 years was difficult at every level, both physically as well as emotionally and mentally. My son was only in kindergarten when I was diagnosed, and I was given horrible statistics up front in terms of my survival likelihood, but I was determined to stay alive, and thankfully for me, I was able to get into CAR T really at the end. And like Navneet said, I would have been going to hospice if the CAR T trial hadn't opened because I had literally burned through six other treatments, none of which worked. Dr. Fumiko Chino: It's truly a transformative treatment, and I can only imagine that for you yourself, the burdens must have been immense. I know that you were an executive flying, it sounds like around the world. How did that change your life? Laurie Adami: So I lost my career as a result of my illness because it was clear after my first relapse, after the only treatment that existed at the time, which was 19 years ago, that this was going to be a battle that wasn't just going to go away. And so, I was really seeking things constantly, and I would do a treatment, it would fail right away. It was really, really difficult at every level. So I had to go out on disability from my work, and then I was never able to go back, because by the time I finally got CAR T, then COVID hit, I couldn't start traveling around the world with my special immune system. Yeah, it was costly at so many levels, but thankfully, thanks to science and all of you doctors on this call for administering these therapies, I am so grateful to be alive. Dr. Fumiko Chino: Well, that segues really nicely in terms of the next advancement of science, which is to take CAR T out of the hospital. Now, Navneet, do you mind giving us an overview of your JCO OP article, outlining key considerations for outpatient administration of CAR T, so discussing things like remote patient monitoring and what is really required in terms of the investments from the cancer center? Dr. Navneet Majhail: Certainly, Fumiko. At the end of the day, as we considered moving these therapies to the outpatient setting, there were two big problems we were trying to solve. One was the capacity issues. I mean, again, we've had increase in the utilization of these therapies, at least across our network, at the rate of like 15 to 20% per year, right? So that's your trajectory where it's heading, and there's a lot more indications coming down the road, and there's no way our health system or any other health system in the US has enough beds on the inpatient side to accommodate this, right? So one was, how do we address the capacity issues that are happening today and that we foresee happening in the future in an innovative way? And the second was, how do we make this therapy more financially sustainable? These are expensive therapies, just by the cost of the product and the care that's given around it. And the more we can do this in the outpatient setting, the less we use inpatient resources, everything that comes with the hospital stay, and would certainly make this more financially sustainable. And I think as we think about moving this to the outpatient side, of course, across our network and for any other place that's considering it, a big component is patient experience and patient safety, right? Because as we discussed early on, there are some potentially really lethal toxicities that are associated with these products. They've gotten better. They are seen less often, and it's not very often that we see those severe toxicities, but they can come up very suddenly. We've got to make sure that you've got the pathways and everything else in place to manage those patients in a safe way. So, we have a multi-site network. We currently have 10 centers that are a part of the Sarah Cannon Transplant and Cell Therapy Network. It's physician driven, and what we do is we like to standardize things as much as possible, so all sites can do the same thing, and we can monitor outcomes, data, and what's happening to patients in that context. So, where we ended up with is using a remote patient monitoring platform to essentially care for these patients in the outpatient setting. It's actually a pretty cool technology and a cool thing our teams came up with. I'm talking about this, but to be honest, I cannot take any credit for what our teams have done. At the end of the day, we currently have a contract with an organization called Current Health. So, they have these kits, which include a remote patient monitoring device. It's an FDA cleared device, and it's essentially something that you slip onto your arm. It's a small, round, an inch-wide monitor. And what it does is it sends data on your vitals, your temperature, your pulse ox, your pulse rate, a whole variety of things, through Bluetooth technology to a central command center that's manned by trained nurses. And what we did was we worked with Current Health to essentially come up with the algorithms for what is a true indicator, potentially true indicator for complications like CRS, right? So if you're sleeping at night, guess what? Your pulse rate goes down, right? If you've just come back from a run, you'll be tachycardic, right? So if you're sleeping with three blankets on you, your temperature will go up, right? So how do we come up with these algorithms which take out the noise and really help us focus on what might be potential CRS? And I'll confess, we are always working to refine these algorithms, make them better as we go forward. Once the nurse sitting in that central command center identifies a potentially true alarm, then we work with them to come up with the triage pathways and the clinical pathways for management so that the patient is triaged to the right care at the right time. So if they end up in the ER, what are the pathways for the ER to give tocilizumab very promptly, right, within 60 minutes of showing up there and so forth. So that is what we have developed across our network from an outpatient care platform, and what we've seen in this context is that we still have around two-thirds of our patients who end up getting admitted in the outpatient setting. So we typically start as a start with the lymphodepleting chemo, and we'll keep it going through at least day 14 after the infusion of the CAR T-cells. And during this time period, around two-thirds of our patients will still end up getting admitted because with the slightest fever, we don't want to take a chance. We'll triage them quickly to the ER or the hospital. But then the median length of stay was only four days compared to our historical data where, as you can imagine, we would keep these patients in for a median of 16 days. So that's how we are managing these patients as we go forward. And like I said, we are doing a lot of research to see how can we make things better, how can we manage some very, very early CRS in the outpatient setting, for instance, and how can we keep refining the alarms and so forth? Dr. Fumiko Chino: That sounds amazing, and it sounds like it's truly something that would not have been capable without some more advanced technologies in terms of remote patient monitoring. So we're truly galvanized by our technologies, telemedicine has really revolutionized, at least during COVID. So I'm assuming you're capitalizing on some of those advancements. Dr. Navneet Majhail: We certainly are, and one of the interesting things I'd like to share, and maybe Laurie can comment on this or may validate this, right? So we collect the survey data, and we talk to the patients about their experience. And one interesting thing that came across these conversations was the fact that many patients and their caregivers felt more secure that there was someone potentially watching them 24/7 for these alarming signs. As you can imagine, as these patients come in, we scare them, right? "Hey, this is very, you know, innovative therapy. This might fix your lymphoma or myeloma, but hey, what, I mean, you got this bad CRS, you know, X number of people will die because of CRS and severe ICANS where you may get seizures and whatnot. But yeah, go home and sleep over it, right? So you can go home, you can stay in the outpatient setting, and come back tomorrow to see us, right?" So it was very interesting to us, that theme where patients felt that, okay, they had a level of reassurance that there was someone watching them. And that to me was very interesting as we collected that data together. Dr. Fumiko Chino: Laurie, is that something that you've heard of from other patients, at least treated in the outpatient setting? Laurie Adami: So I have not actually spoken to a patient who's had the monitoring on them. I've spoken to numerous patients who've done it outpatient and have been very scared, and their caregivers have been even more scared, because you know, not all caregivers are created equal. Some of these patient populations are older, and you know, there can be confusion. So, you know, I think the fact that these monitoring devices are going to become available will be immensely helpful, not only for the patient's well-being, but for their caregiver who's right now on the hook. If they fall asleep and miss the patient spiking a fever, I mean, this is the scary stuff. So, I think this is fantastic. I do wonder how you manage, how you figure out the ICANS part of it, because I know the symptoms you're talking about are primarily CRS. So does the monitor do anything that can gauge the mental activity or no? Dr. Navneet Majhail: We are spot on that the monitoring is mostly focused around CRS. Now, for example, our program here in Nashville, the process we…
